A young mother, carrying her baby, and begging in the street. India is a country of stark contrasts – immensely rich people, but also masses of totally vulnerable, poor people.

For us westerners, such poverty is extremely difficult to come to terms with. Nobody can help everybody in need, but it is not easy to turn a blind eye, and ignore the thin fingers tapping on your arm. Give to one, and there will soon be dozens more swarming around you, and they just won’t leave you alone.
